Each year the U.S. Department of Energy sponsors a competition for the design of a home that can maximize the energy of the sun for affordable, sustainable living. This year, the team from the University of Maryland took home the competition’s top honor for their project entitled: Watershed. Rather than a visual manifesto on the rebranding of the single family home, the success of the design revolves around the integration and interconnection of a series of technologies and systems to create a compact, efficient and welcoming residence. The result can serve as a model to progressive home building in many ways–an area where our country needs no shortage of help in understanding how sustainability can be integrated into everyday living.

Merely building a small home that gathers the most solar energy would not snag you the blue ribbon in this competition. The Solar Decathlon is judged on a series of criteria including affordability, engineering, communications, comfort zone and market appeal. This is integral to the success of the challenge because despite the fact that sustainability’s public image may revolve around solar panels and wind turbines, the true meaning of the word is a holistic notion of balance that affects all aspects of living.

The drive to stem the use of coal for power production in the U.S. has gained considerable traction over the past decade. According to some sources, coal power holds the title of the single largest source of air pollution in the country while its supply chain contaminates every resource that it touches. Removing coal from our energy portfolio is one of the greatest sustainability milestones that Americans could hope to achieve, but the goal might benefit from a simple tactic that brings the core issues closer, or rather into, the homes of consumers. To deter the use of coal power we may need to reach for a blunter instrument.

For most Americans, the concept of “power” is little more than a number that comes in the mail. The distance between the act of power production and the resulting charge on an electrical bill is a key ingredient to how energy companies keep the disturbing realities of our grid outside the focus of their own consumers. Closing that gap could be as easy as bringing that information front and center with warning labels that remind the consumer exactly what their dollars are buying. Slapped on the front of envelopes or next to the amount due, the reoccurring reminder could help educate people of the repercussions of their energy use and either promote increased efficiency or the choice to make the easy switch to paying for greener power.

For the first time in a while, our portfolio of renewable power sources has surpassed power production from nuclear generation. According to the latest Monthly Energy Review from the Energy Information Administration, the most sustainable forms of energy now produce more for us than the most hazardous, largely due to rises in wind, solar and hydro production.

Most of the time, when we think of things being built the majority of hours it takes to complete a project revolves around construction. It is rare that an architect will spend more hours drawing a project than a contractor will take to build it. For residential solar installations, the growth in demand is being met by a regulatory system not fully prepared for the expanding market. As a result, a large portion of the cost for new PVs pays for people sitting at a desk rather than throwing up panels.

In virtually every industry and profession we can point to occurrences of codes and regulations that create needless amounts of red tape, adding unnecessary time to the schedule and taking away valuable resources from the budget. By most businesses, regulation is seen as a hindrance that opposes free market capitalism and, as such, should be minimized. But a complete lack of regulation, even in a fundamentally good pursuit like sustainability, can not only produce a series of liabilities but specifically those that undermine the very goals that sustainability is trying to accomplish.

I recently wrote an article describing geothermal heating and cooling, making no secret of my strong support for the technology and its implementation. On the mainstream of residential construction, geothermal is still rather new so many municipalities are still trying to catch up to the learning curve of the repercussions of installing new wells without hindering the expansion of the budding industry. In doing some research on geothermal for a project in Rhode Island, I came across a surprising interface of regulatory oversight and sustainability that underscores the conversations that they need to continue to have.

When it comes to the question of how to heat and cool our homes, there is a great answer right under our feet. A client recently expressed interest in exploring geothermal for a home renovation in Rhode Island and I wasted no time in jumping on the opportunity to cement it as one of our goals for the project. Despite Americans’ slow adoption of the technology, geothermal offers an efficient and sustainable way to let the earth do most of the work in heating and cooling a home. It also offers one of the best solutions to target energy efficiency and the reduction of reoccurring fossil fuel use. Continue Reading…

Our country’s effort to support renewable energy is still in its early stages of development and ripe for adjustment. The maturing of the renewable industry can positively affect job growth, technological innovation and increased efficiency, but there are a number of ways we can be doing those things, even within the umbrella of sustainability (smart grids, alternative transit infrastructure, electric cars, building systems,etc.) The real goal of governmental support for renewables should be getting more clean megawatts attached to the grid. If that is the goal, then we should be retooling our system of incentives to make that goal a reality rather than dilute its effectiveness due to a lack of focus.

Many developing countries look to our utility grid with envy. Our access to technology and capital allow us to stretch services to just about anybody, but there is a point where a locality’s dwindling population density no longer warrants connection to the greater grid. With the amount of unavoidable renovation on the horizon and our increasing goal of making a more sustainable system, our grid should be retooled by density-driven metrics. Those areas that fall below a certain density threshold should not only have to supply their own services on site, but do so with sustainable systems.

Collaboration between professions can yield new, uncharted perspectives that lead to fresh ideas and in doing so, Grimshaw Architects has pushed the boundaries of what the perceived role of an architect actually is. With international engineering firm ARUP, Grimshaw has helped to design a new conceptual model of an offshore wind turbine dubbed the Aerogenerator X. The design is not only an example of what complimentary industries can accomplish together, but how the face and appearance of sustainability can be re-imagined beyond the icons that we are used to.

The growing buzz around electric vehicles has some saying they will be the next great product migration in the automobile market. To date, one of the largest impasses for the fledgling technology is the batteries and their expense. Advanced battery systems, like lithium-ion, required for larger capacities and quicker recharging times are the high cost element for these new cars. But some car companies are now exploring a way to help offset those costs and materials by trying to survey out a second life for these batteries after they leave cars to serve as renewable power storage. Before electric vehicles have even hit the production lines their lifecycle costs could be drastically reduced by capitalizing on interconnections with other sustainable industries.
